I am truing one of my .308's into a .223 new bolt head for my Bighorn TL3 SA with a Shilen 7 inch heavy Palma barrel in one of my MPA hybrid chasse. I have a new Bighorn TL3 left hand action with a Bartlein 10 inch left hand Trist heavy Palma 31 inch and a new manners MCS-T6A stock I only need the stock and Shilen barrel.
